“None, sir.”

“Is that true of you, Wilson?”

“I?” exclaimed Kit. “No, sir; that is, sir, I have been there once before, but only on the outside and looked in at the windows.”

“And you, Deering?”

“No, sir, I have never been there before.”

Dr. Forester had turned on Tony like a flash. “How then do you account for the fact that a letter addressed to you was found there this afternoon?”

“A letter addressed to me found there!” exclaimed Tony, in surprise. “I can’t account for it. I do not know how it got there.”

“Do you know of other boys being there?”

“I believe other boys have been there; yes, sir.”
